. SPECIFICATION forming part of Letters-'Patent N0.754,784, datedrlkvarch 1.5, 1904.

Application filed August,6,1903. l

To all whom #may concern:

Be it known'that I, HERMAN LINDENBERG, a citizen of the United States, and a resident of West Hoboken, in the county of Hudson and State of New Jersey, have invented new and useful Improvements in Apparatus forv Treating Yarn, of which the followingis a full, clear, and exact description:

The invention relates to` certain noveland useful improvements in machines for treating yarn, and has particular application to an apparatus of the type referred to wherein the yarn may b e subjected to a bath of any suitlineated in thejaccompanying drawings, andv ablechemical and subsequently immersed in a cleansing-bath. A. Y

f In carrying out the present invention I have in view as an object the provision of a machine upon which the yarn to betreated is placed and held under tension while it is rotating' and while subjected to a bath of suitgbll chemical and subsequently to a cleansing- A further object of my invention is to pro- -vide a vat or tank'designed to contain the solutions in which the yarn' is to be immersed,4

such tank being rotatably movable and vertically adjustable relative to the yarn-carrying devices of the machine.

` Finally, I have in View as an object the provision of 'a machinewhich shall embody the essential and desired Vfeatures of simplicity,l durability, positiveness of operation, econo-` my, and convenience.

With'the above-recited objects andothers of a similar nature in view my invention con# sists 1n the construction and arrangement of parts, asis described in this specification, de-

l set forth in the claims.

Reference is to be had to the accompanying drawings, forming ,a' part of this specification, in which similar characters of reference indicate corresponding parts .in all the figures.

andFig. 8 is a top plan View of `the'iiiovable y frame members of the machine andthe locking devices for the same. l

As is well known, in the treatment of'ya'rn it is desirable and often I necessary to subject the same to a bath of suitablechemical and subsequently wash or remove the chemical from the material by immersing4 the yarn in a bath of water. This process is usually extremely tedious, and in order tov accomplish the same in a-simple manner I have devised an apparatus which I'will now proceed to describe in detail; v Y l A Referring now to the drawings in detail,

indicate a pair of parallel standards .or ,frame members designed to be rigidly secured to the Hoor or platform, each of said members bef ing provided at its upper end with ahorizon-A tal extension 5%- Arranged opposite the aforesaid frame members 5 5, but spaced `apart some .distance therefrom, so that a v at or its attachments may be interposed therebetween, are the'frame members 6 6, similar in construction to the members 5, but instead of being, rigidly'secured to the floor or platform said framemernbers 6'are` hinged or piv.-

ote'd, as at 7, sov that they may be swungy towardand from the members 5, and it is further to be noted that the standard or frame members 6 areprovided with horizontal extensions 61, similar to the extensions 5a. Connected with the frame members 5 5 is an additional supporting-frame 8, said additional frame being designed to act as a support for the power-transmitting devices of the apparatus. Depending from each of the extensions 5a is a vertical hanger-arm 9, while adjacent to the extensions 6L of the movable frame members 6 depend similar hanger-arms 1,0, said arms extending parallel with the arms 9. The hanger-arms 9 and 10 are provided centrally with enlarg'fed'` bored portions 11 1.1 and 12 12, while the lower free ends of the arms are provided with bearing-collars 13 13 and 14 14. Extending 'transversely between the arms 5 and 6*L and supported partially by the enlarged bores `l1 and v12` and the arms themselves are the parallel horizontal shafts 15 15, said shafts finding bearing at one end lin the additional framework 8. In order to cause the revolution of the parallel shafts 15 15, each shaft is provided at one end with a gear-wheel 16 16, said gear-wheels intermeshing with the gear-wheels 17, mounted on the relatively short power-shaft 18 which latter shaft is journaled in the framework 8 andin the cross-bar 19, extending vbetween the extensions 5'3L 5". Journaled in the lower yends of the hanger-arms referred to are the paral- 1el`shafts20 20,'said shafts being driven by means vof endless chains 21, encircing the ends of the shafts 20 and theends of the shafts 15, so that when `said shafts l5 are rotated the shafts 20 wil-l also receive motion.

Loosely mounted upon each of the shafts 15 are the bearing-boxes 22 22, there being a pair of such boxes for each shaft, and supported by each pair of boxes is a roll 23,

which .for the purpose of convenience I will hereinafter term the tension-roll. As stated,

the boxes are loosely mounted upon the shafts 15, and in order that they may be swung or oscillated upon the shafts I provide for each box a lever 24, each of said'levers carryin'ga latch-lever 25, which is designed to .engage- Witha toothed segment 26. It will be noted that there are four of these segments, one for each extension of the frame members, the mounting of the segments being clearly shown in Figs. 1 and 2.

From the description thus lfar given the manner of placinga skein or hank of yarn upon the machine will be readily apparent. One of the movable arms is swung out and the skein is lifted over the top of one of `the levers 24 and placed around the shafts 15 and the shafts 2() immediately below the same, so that the loop or skein will be somewhat elliptical in form when carried by said shafts. As the machine is practically a double apparatus, two

' skeins may be placed'upon the machine at-the same time, each skein being carried by an up` per shaft 15 andaglower shaft 20. In order to give the skeins the proper tension, the le vers 24 are moved outward, as is shown in Fig. 1, thus swinging the tension-rollers inward to.

ments, one for the water and the other for the solution. This tank isprovided with a number of casters or rollers 29, designed to travel in the grooved track'30 on the floor or platform, so that the tank or vat may be easily turned to bring the solution-containing compartment or the bath directly beneath a certain skein of yarn. Secured to the central bottom portion of the tank is a post 31,adapted to be movable within a supporting tubular standard 32, rigidly secured to the oor, and in order to accomplish the moving of the post .within the supporting-standard I provide the former with a toothed rack33, adapted to mesh with a gear-pinion 34, carried at one end of the horizontally-disposed shaft 35, the oppositey end of said shaft finding bearing in the lower portion of the frame 8. Motion is imparted from the power-shaft 18 when the `latter is driven by the belt-pulleys a; anda' through the medium of the endless drive-chain 36, ex-

tending over the sprocket-wheel 37 on .the

shaft 18 and over the sprocket-clutch mern'A be'r'38, loosely mounted upon the vhorizontal shaft 35.` The opposite member of the clutch, which I have shown at 39, has slidable engagement with the shaft 35, so that when forced into coaction, the member 38, through Athe mediumof the pivoted lever 40, power will be given the shaft 35 to revolve the same, and the pinion 34, working over the rack 33, will cause the elevation of the vat. In order to check the vertical movement of the vat, yI have provided a braking mechanism consisting of the band-pulley 41, mounted upon the shaft 35, so that the clutch member 39 is interposed IOO IIO

between the sprocket-clutch 38 and said pulley. This clutch member 38 is so formed that itis at all times in engagement with the pulley 41, the latter turning loosely on the shaft, and its motion is checked through the medium of a band-brake 42, encircling the pulley and operated by the lever 43.

The retention of the hinged members 6 6 against movement is accomplished by the following devices: Pivotally mounted uponeach extension 6 is a latch 44, adapted to engage with the adjacent top portion of one of the hanger-arms 10, and each of said latches is held against movement by a locking-bar 45, pivoted, as at 46, to the top portion ofthe frame` member. For the purpose of acting as a stop for the tension rollers I have supported,

III;

through the medium of each pair of shafts 15 and 20, a central bracket'457, said bracket having a curved enlargement 48, formed intermediate of its length, in which the roll 23 is designed to seat `when in its normal non-tensioning position.

From the drawings it will be seen that it is only necessary to move the locking-bar, thereby releasing the latch and permitting the arm to` be swung upon the pivot 7 outward from the apparatus, so that` the yarn will be readily passed over the hanger-arm and tensionroll lever onto the yarn-carrying shafts. It is further seen that when the frame members are swung outward the toothed segment-sections 26 26, secured to the members, are of course swung outward therewith, this arrangement being formed in order that no obstruction may be met with in passing the yarn over the levers and upon the shafts.

From the above description, takenin connection with the accompanying drawings, the construction and operation of the entire apparatus will be readily apparent. The skein of yarn to be treated is slipped over the levers and upon the shaft after the frame members have been unlocked, and said members are then moved back into position and locked to the adjacent vertical hanger-arms. The tension-shafts are then moved inward toward the center of the machine by actuating the levers 24 until the yarn is held at the desired tension. The tank is then elevated by the mechanism hereinbefore described until/the skeins of yarn are entirely submerged, one skein being subjected to the chemical bath,'while the opposite skein is immersed in the water-bath.

.The tank may then be turned and the skein previously subjected to the chemical is submerged in the water, the shafts in the meanl time imparting rotary motion to the train of power devices in order to cause the skein to travel over the same, so thatkthe yarn will be thoroughly treated. The tank may be lowered after the treatment has been completed and the skeins removed therefrom and new ones substituted.

From the above description it will be seen that the yarn receivesr thorough treatment, and the operation consumes but little time when com pared with the methods now in use. It will also be noted that with a machine of this character the hanks or skeins of yarn may be I placed upon and removed without stopping the machine. This is a great advantage, as it enables the work to be accomplished with the least possible delay.

While l have shown and 'herein described one particular embodiment of my invention, it is of course to be understood that I do not limit myself to the precise details of construction shown herein, as there may be modifications and variations in certain respects withoutdeparting from the essential features of the invention or sacrificing any of the advantages thereof.
